Rainwater and Greywater Harvesting Systems for Commercial and Institutional Buildings

Welcome to Water Harvesting Solutions!

Commercial buildings can save millions of gallons of potable water each year by harvesting rainwater, grey water, condensate and other on-site sources for non-potable uses like toilet flushing, irrigation and cooling tower make-up. Wahaso provides complete design/build systems custom-tailored to each building.
Rainwater harvesting is the most common system type, and Wahaso specializes in commercial rainwater harvesting systems. Unlike the more simple systems installed for homeowners, our rainwater harvesting systems are designed with the commercial-grade components and sophisticated controls required in commercial buildings for reliability, automated functions and connectivity to BAS systems.
In geographies where rainwater is less abundant, greywater (gray water) can be an excellent source for harvesting. Greywater harvesting systems collect water from showers and sinks and other
"gentle" uses that can be safely and effectively treated for many non-potable uses.

Our Mission

Our mission at Wahaso is to help municipalities and commercial property owners reduce the impact of their buildings on the environment through innovative sustainable water practices.

We believe that some form of water harvesting and reuse can be both economically and environmentally viable for all commercial buildings.

Design Build Services

When a building is being designed, we scope the harvesting system by thinking through the best sources and uses for on-site treated water. We recommend the size and type of system and provide a rough estimate of the project's cost.

We serve as the manufacturer of the specified system. We pre-assemble and test all components at our facility and then ship them on skids ready to be installed as an integrated system by the local contractor.
